快速背景——我需要找到通过我们公司实验室的案例的终止率，这些案例按案例类型和月份分组。到目前为止，我想出了这个：

SELECT BPI.TYPE,
       EXTRACT(MONTH FROM CS.RECEIVED_DATE) MONTH,
       COUNT(*) termed_cases
  FROM CELL_SOURCE cs
  JOIN BASIC_PATHOLOGY_INFO bpi ON CS.CELL_SOURCE_ID = BPI.CELL_SOURCE_ID
  JOIN RECENT_CELL_SOURCE_STATUS rcss ON CS.CELL_SOURCE_ID = RCSS.CELL_SOURCE_ID
 WHERE type IS NOT NULL
  AND CS.RECEIVED_DATE > to_date('03/01/2011', 'MM/DD/YYYY/')
  AND RCSS.STATUS like 'Term%'
GROUP BY BPI.TYPE, EXTRACT(MONTH FROM CS.RECEIVED_DATE)
ORDER BY month, type

这发现所有已命名的案例都很容易。但是，当我想找到汇率时，我遇到了一些问题。我尝试使用子查询来捕获每种类型的案例总数，无论其状态如何，例如：

COUNT(*)/(SELECT COUNT(*) 
            FROM CELL_SOURCE cs_1 
            JOIN BASIC_PATHOLOGY_INFO bpi_1 ON CS_1.CELL_SOURCE_ID = BPI_1.CELL_SOURCE_ID
          WHERE BPI_1.TYPE = BPI.TYPE 
            AND EXTRACT(month from CS_1.RECEIVED_DATE) = EXTRACT(MONTH FROM CS.RECEIVED_DATE)) termed_cases

但是，这会引发ORA-00979: not a GROUP BY expression错误，并BPI.TYPE从子查询中突出显示。

任何人都知道我的错误实际上可能是什么？另外，分析函数在这里会比聚合函数更好吗？

因此，您需要两个计数：当月所有案例的总数和仅 Termed 案例的总数。最简单的方法是使用 CASE() 函数执行条件计数，如下所示：

SELECT BPI.TYPE,
       EXTRACT(MONTH FROM CS.RECEIVED_DATE) MONTH,
       COUNT(*) all_cases,
       sum(case when RCSS.STATUS like 'Term%' then 1 else 0 end ) termed_cases
  FROM CELL_SOURCE cs
  JOIN BASIC_PATHOLOGY_INFO bpi ON CS.CELL_SOURCE_ID = BPI.CELL_SOURCE_ID
  JOIN RECENT_CELL_SOURCE_STATUS rcss ON CS.CELL_SOURCE_ID = RCSS.CELL_SOURCE_ID
 WHERE tumor_type IS NOT NULL
  AND CS.RECEIVED_DATE > to_date('03/01/2011', 'MM/DD/YYYY/')
GROUP BY BPI.TUMOR_TYPE, EXTRACT(MONTH FROM CS.RECEIVED_DATE)
ORDER BY month, tumor_type

请注意，我已从 WHERE 子句中删除了 LIKE 过滤器。
